Boolean isn't making holes

Hey!

I’m trying to do holes in a bigger model using of course a smaller model with mesh. Unfortunatelly it does not work. I tried every option of it. Earlier I was using normal face/edge filling but when I wanted to dissolve some edges I had limited boundary thing. I hope someone will explain why does boolean isn’t working or maybe show me a new option? :slight_smile:

Greetings!

Boolean does not work well when there’s no volume. If there’s no volume, where’s the “inside” and the “outside” of things?

A way to do this shape: Join all the meshes into one, delete only the faces, then go selecting vertices that form convex regions, and make faces with them.

[EDIT]
Remove double vertices once you have joined the shapes, it will give you less headaches when you start constructing faces.
